Figure 3. Comparison of expression patterns for
pes-1 and T14G12.4 (
fkh-2) reporter gene fusions. The C. elegans embryos have approximately 185 cells and are orientated with anterior to the left.
pes-1::gfp (A) and T14G12.4::gfp (B) reporter gene fusions are both expressed in the 4 descendants of the D blastomere, toward the posterior. Expression of T14G12.4::GFP is weaker and not as restricted to the nucleus as PES-1::GFP. Expression is also observed more anteriorly but these expressing cells do not seem to be identical for the two genes. Scale bar in B, 10 µm.
